Hi Guys and Girls, need some help from some Busa riders. I just bought and 04 Busa and had a machanic look at it because when I turn the handlebars all the way left the choke cable pulls in the choke and the RPMs shoot to about 2Gs. The machanic says there is no fix to just not turn the handlebars too much left, but that's kind hard not to do when I'm trying to make a U'e on a two lane road. Has anyone else had this problem and if so what's the Fix?

04 busas werent fuel injected? REALLY?

FastCat · 08-15-2008, 12:49 AM

Technically-speaking it's a F-idle not a "choke" but same-same as far as the cable is concerned. My bet is that either the wrong cable is fitted or it's routed improperly or both.

Mr_Schexy · 08-15-2008, 02:19 AM

The machanic thought the same and said the cable is the right cable and routed right but said that's just the way it is. There has to be a fix somewhere cause that kinda dangerous.

Whoever told you that is mistaken. You are correct. It is dangerous. There may be an adjuster built-in to the cable itself, or there will be one on the throttle-body where it attaches - you need to put some more slack in the cable so you can go from full-lock left to full-lock right without changing the idle-speed. If you cannot adjust/route the cable so this is possible, something is definitely wrong.

Mr_Schexy · 08-15-2008, 03:38 AM

The machanic and even I adjusted the cable to full slack with the same results. This is why this is frustrating.

Just sell it and buy a honda!

So what does a new choke-cable cost, like $15? $20? If you buy a new one and fit it and it changes nothing, you're not out much and at THAT point you can rest assured that the cable itself is not the problem. That's what I'd do.

Does your bike have any kind of bar risers, like heli-bars?

The mechanic is completely wrong. If you do have bar risers, you need to reroute the cable. For heli-bars it goes between the two screws that hold down the tank. If you don't have bar risers, and you can't adjust it out any further, you need a new cable.

I adjusted the freeplay in my throttle tighter...ever since then it revs slightly but only at FULL lock. Not something that is an issue at all.. If it only goes up when the bars are turned completely, who cares? The only time you'll have it at full lock is when the clutch is dissengaged and both feet are on the ground....

Mr_Schexy · 08-15-2008, 05:24 PM

no, no risers,or heli-bars

TruWrecks · 08-15-2008, 06:04 PM

Definitely sounds like the wrong cable is installed, or it is not routed correctly. I had an 04 LE that didn't do that at full lock on either side. Get a new mechanic. The one you have is defective.

Talk to Cloud 9 Motorsports in Boring. Daniel will take good care of you. He knows the Busa.

Daniel is good people. If he doesn't know the answer, he will tell you so.

it is a cable issue. either the fast idle cable is misrouted, wrong or mis adjsuted or the throttle cables are not slacked enough or mis routed.

aslo check the cable mount on the throttle body. i have run across a few bent ones that kept the cables from being adjusted properly.

all cables should be routed out the right side of the steering head, then forward of the top clamp. the throttle cables need to be routed to the right and not twisted and the fast idle to the left. they do not go trought he ram air tubes nor do they go through the area over the radiator. i see plenty of them routed all screwed up.

aslo make sure the air box is not causing the cables to get crimped or restricted of movement.

Mr_Schexy · 08-15-2008, 11:34 PM

Ok I'll try that and see what happens, Thanks.

You need to go to another mechanic. Seriously....

The bike is NOT supposed to do that.

Get a busa tech manual off e-bay for like 20 bucks and check the cable routing.

Look for pinch points, etc... it could be as simple as someone put a tie-wrap where there isnt supposed to be one, or tightened one too tight, etc...

But it is most definitely NOT supposed to be like that.

You have taken too much slack out of the throttle and this is not a good thing to do.

Took it to a new machanic it O' City yesterday and he rerouted it to the left of the tripletree bolt and under the tank and it works just fine, so thanks for all your info.

that is still the inccorect routing. the factory routing is to the right of of the tree as i described previously.

take a look at where all 3 cables run in this picture, never mind that my throttle bodies are upside down. that is the factory routing.
